We have made several trips we enjoyed, FWIW :
- Nashville, TN (lots of historical / civil war / plantation / museums) within appx 30/40 mile radius. We stayed at Nashville KOA on Music City Dr, so many food & shopping & of course Opryland and other country music buff sites.
- Cave City, KY (Mammoth Cave / civil war / museums) within appx 30-40 mile radius. We stayed at Cave Country RV park, and food / shopping. Also, Corvette Museum is interesting and easy close by.
- Lexington, KY (horse lovers paradise / civil war / museums) within appx 30-40 mile radius. There are state parks, or many like to stay at KY Horse Park campground. I-75 S from Cincy is a great smooth road and makes it easy to stay a bit south of Lexington but still be close for toad trips to city. KY Horse Park is worth at least a day, maybe two.
Others will have good ideas to share I am sure. So, whatever your destination, Safe Travels To All
